Abstract
Un método y aparato para radiografía, y especialmente para radiografía de haz plano y también un detector para detectar radiacion incidente. En el método yel aparato, en donde los rayos X (9) son emitidos desde una fuente de rayos X (60), a losrayos X se les da forma de haz plano y son transmitidos a través deun objeto a ser radiografiado (62), y los rayos X transmitidos a través de dicho objeto (62) son detectados en un detector (64). El detector (64), el cualdetecta radiacion incidente,es un a cámara de avalancha gaseosa de placa paralela, incluyendo montajes de electrodo entre los cuales se aplica un voltaje paracrear un campo eléctrico, el cual causa avalanchas de electrones de ionizacion primaria y secundaria liberados por laradiacio n incidente. El detector (64)está orientado, en relacion a la radiacion incidente (9), de modo que la radiacion entra lateralmente entre una primera y una segunda placa paralela, entre lascuales se crea el campo eléctrico. Las senaleseléctricas indu cidas por dichas avalanchas de electron-ion son detectadas por lo menos en un montaje deelectrodo detector, incluyendo una pluralidad de elementos de electrodo de detector acomodados adyacentes entre sí, cada uno a lo largo de unadireccion que esese ncialmente paralela a la radiacion incidente. Los pulsos desde cada elemento de electrodo de detector son procesados en electronica de procesamiento, paraobtener valores para cada pixel correspondientes al respectivo elemento deelectrodo de detectorA method and apparatus for radiography, and especially for flat beam radiography and also a detector to detect incident radiation. In the method and the apparatus, where X-rays (9) are emitted from an X-ray source (60), X-rays are shaped as a flat beam and transmitted through an object to be radiographed (62), and the X-rays transmitted through said object (62) are detected in a detector (64). The detector (64), which detects incident radiation, is a parallel plate gas avalanche chamber, including electrode assemblies between which a voltage is applied to create an electric field, which causes avalanches of primary and secondary ionization electrons released by incident radiation. The detector (64) is oriented, in relation to the incident radiation (9), so that the radiation enters laterally between a first and a second parallel plate, between which the electric field is created. The signals induced by said electron-ion avalanches are detected in at least one detector electrode assembly, including a plurality of detector electrode elements adjacent to each other, each along an direction that is essentially parallel to the radiation. incident. The pulses from each detector electrode element are processed in processing electronics, to obtain values for each pixel corresponding to the respective detector electrode element.
